[petsc-dev] Petsc: Error code 1 TS adapt difference

[Barry Smith]

   Emil and Hong,

   In this test the GLEE time step adapter is making a different decision on accepting or rejecting a step. It could be due to slight differences in round-off for different machines and compilers. I leave it to our ODE experts to take a look at it.

And I get the error code 1 in different tests on different machines.I don’t know what is error code1. What case this? How can I fix the failure tests.
